[Haskell-cafe] SDL program under MinGW

Yes, with some modifications.

I used SDL-1.2.13, not SDL-1.2.12.

Also, my Include-Dirs has include\SDL, not include:

If I don't put include\SDL, I get errors like
Graphics\UI\SDL\General.hsc:1:17:  SDL.h: No such file or directory

And I used the following command to configure:
C:\Users\client\Downloads\SDL-0.5.4>runghc Setup.lhs configure
--prefix=C:\Users\client\haskell --datadir=$prefix\share --user

it builds and installs fine. I only get linker error (undefined
reference to SDL_main) when I compile a program that uses SDL binding.
